The Idea of "Happiness"

Who is a happy guy? A really genuinely happy guy. The feeling of satisfaction,comfort,relief etc. are not to be confused with what I am concerned about.You would think a man getting a job he badly needed would give him happiness but if you really think about it for a second,relief would be a much more accurate word to describe his feeling.Maybe when a mother penguin finally after a long battle with the sea waves is able to bring food for its newborn baby it feels happy and again I dont think her small successful victory against nature's  fierce force would make her anything more than relieved for the rest of the day as she embarks on the same journey next day .Now what if the feeling of pure happiness is not even a real thing?what if "happiness" is nothing but just the mixture of all those emotions?It is quite possible but not the answer I hope is true.
